Methods for experimental investigations on tyre-road-grip at arbitrary roads

  • Having a look at safety to traffic and the prevention of accidents it can be observed that technical improvements in active safety of vehicles have let to various positive effects in this area. Among other components the tyre-road-contact takes a key role in the development of active safety technologies. All forces in accelerating, breaking and vehicle guidance have to be transmitted through the tyre-road contact area by friction forces. A common way to characterize a friction process is to identify the coefficient of friction μ between two touching materials. Even though there are several approaches to experimentially characterise road surfaces, no standard method exists. In this paper an overview of existing test methods is given. Furthermore the preliminary design of a newly developed portable test device with its possibility to investigate the tyre-road-friction of arbitrary roads or even places of accidents is shown.
